IMPRVEMENT IN SEEDING-MACHINES.

Speciiication forningpart of Letters Patent No. 36,07* dated August 5,1662.

l vention, taken on the line .fr x, Fig. 2. Fig. 2

is a plan or top View ofthe same. Fig. 3, adetached section ot' aportion ot' the saine, taken in the line y y, Fig. 2.

Similar letters ot' reference indicate corresponding parts in theseveral figures.

'lo enable those sli'illed in the art to fully understand and constructmyinvention, I will proceed to describe it.

A representsa rectangular trame, which is mounted on two wheels,B which`are attached trmly to vtheir axle C, the latter being allowed to rotatein the frame A.

D is the drivel-s seat, which is attached ccntrally to a bar, E, securedto the upper ends ot' springs or elastic supports F F, on the backpai-tot' the trarne A and Gr is thedraftpole, the back end ot' which isconnected by a inetalstrap, a, with the axle C, the latter being'allowed to turn freely within the strap.

H represents the teeth or small coveringshares, which are attached tothelower ends of inclined bars I, the upper ends of the latter being fittedloosely on a rod, J, which passes transversely through the frontpartofthe frame A and through the back part ot' the draftpole G.

J isa rod, the ends ot' which project beyond the sides or the frame A,and 'upon it there is itted loosely a frame, K, composed of two parallelside bars, b b, connected by a cross-bar, c. The back ends of the sidebars, b b, are itted on the rod J', as shown clearly in Fig. 2, and tothe front side ot' the. cross-bar c the lower ends ot' the tooth-bars Iare connected by chains d.

On the frame K there is placed a seed box or hopper, L, which extendsthe whole length ot' the frame, and is permanently attached thereto.This seed box or hopper has a slot, e, in its bottoni extending thewhole length of the latter, the sides of the bottom adjoining theslotbeing inclined,asshown atffin Fig.1.

On the frame K there is placed a slide, M, which is perforated withthree parallel rows of holes, g 0, and the ends of the slideA M areattached to twoparallel side pieces,N N, which are also perforated, andare connected at their front ends by a cross-bar, 0. The slide M worksunder the main portion ot' the hopper containing the slot e, whiletheside pieces, N, work under small hoppers P P at each end ot' the hopperL. The ends ot' .the cross-bar 0 have tenons hh on them, which arefitted in the. front'ends ot' connecting-rods Q, Q, the back ends ofthelatter being attachedto the wheels B-B at a suitable distance from theircenter.

From the above description it will be seen that as the machine is drawnalong a recipro eating motion will be given the slide M, and as theperforations gpass underneath the slot e the former become lledwithseed, the latter being discharged as the holes pass out from underneaththe bottom ot' the hopper at its front and back sides. The dischargedseed falls upon an inclined board or scatterer, R, which is attached tothe draftpole G in such a position as to receive the seed and canse itto drop in a broadcast manner directly infront of the teeth on smallshares H.

rlhe pertoratedside pieces,N N, which worlt underneath'the small hoppersl), are for the purpose ot' dropping corn in hills, and tubes lt areattached to the side bars, b b, ofthe frame K for the purpose ot'conveying the corn to hollow shares S, which are attached to the lowerends ot' the tubes lt and form the fnrrows. (See Fig. 3.)

To the wheels B, at their peripheries, there are attached a series ofmarkers, lT, which are composed ot' flat metal plates projecting fromthe inner sides ofthe wheels', as shown in Fig.V

2, said plates being attached to the wheels at such points as to pressthe earth'on each dropping ot' seed and mark the saine. At any time whenit is necessary to raise the teeth H the operator from his seat Ddepresses the haelt end of a lever, U, the front end ot' which isconnected by a rod, W, to the hopper, and thereby raises the frame K,and consequently theteeth H.

' The forward and backward movement of the perforated slideM ispreferable to the ordinaryiongitudinallyorlaterally movingslides, onaccount of the former not being so liable'to choke or clog. '.lhelaterally-moving slides not upon the seed in ndirection longitudinallywith the seed box or hopper, and are not so liable to agitate 4 it,Whereas the forward and backward movement of the slide, as in myinvention, acts upon Iche seed in the direction of the width of thehopper, and has n. greater tendency to agitatethe seed and shake it'.down in the. hopper. rPhe means of operating the slide is also muchsimpler and less lisible to get'I ont of repair than any that can beetnployed for operating the laiterall'ymoving slides.

I would remark that'the Wheels BBm'ttv be attached firmly to an ironletxle, with cranlat euch end to work the pitmnn that; moves the slidesbeneath the seed-box,tl1e axle being allowed to rotate in the frame Aand one ofthe wheels attached permanently to it.

Having; thus described my invention, what I claim as new, and desire ,tosecure by Letters v 1. The attaching of the hopper or hoppers to a.frame, K, bung or placedA loosely ou the rod J', in combinationv withthe tooth-bars I. connected at their lower ends by chains d to thefreine K, Iind vfitted at their back ends CASTLE CHURCHILL.
